Digital Principles and System Design

PREFACE OF THE BOOK This book is extensively designed for the second semester CSE/IT students as per Anna university syllabus R-2013. The following chapters constitute the following units Chapter 1 and 2 covers :-Unit 1 Chapter 3 and 8 covers :-Unit 2 Chapter 4 and 5 covers :-Unit 3 Chapter 6 covers :- Unit 4 Chapter 7 covers :- Unit 5 Chapter 8 covers the Verilog HDL:- Unit 2 and 3 CHAPTER 1: Introduces the Number System, binary arithmetic and codes. CHAPTER 2: Deals with Boolean algebra, simplification using Boolean theorems, K-map method , Quine McCluskey method, logic gates, implementation of switching function using basic Logical Gates and Universal Gates. CHAPTER 3: Describes the combinational circuits like Adder, Subtractor, Multiplier, Divider, magnitude comparator, encoder, decoder, code converters, Multiplexer and Demultiplexer. CHAPTER 4: Describes with Latches, Flip-Flops, Registers and Counters CHAPTER 5: Concentrates on the Analysis as well as design of synchronous sequential circuits, Design of synchronous counters, sequence generator and Sequence detector CHAPTER 6: Concentrates the Design as well as Analysis of Fundamental Mode circuits, Pulse mode Circuits, Hazard Free Circuits, ASM Chart and Design of Asynchronous counters. CHAPTER 7: Discussion on memory devices which includes ROM, RAM, PLA, PAL, Sequential logic devices and ASIC. CHAPTER 8: Introduction to Verilog HDL which was chosen as a basis for the high level description used in some parts of this book. We have taken enough care to present the definitions and statements of basic laws and theorems, problems with simple steps to make the students familiar with the fundamentals of Digital Design
